  • Publication number: 20130068500
    Abstract: The present invention provides an insulated wire having a conductor and at least two insulating coating layers formed surrounding the conductor, wherein the insulating coating layers comprises the outermost layer thereof, which has a thickness in the range of 20 to 50% based on the total thickness of the insulating coating layers and comprises a polyimide resin; and a base insulating coating layer in contact with the conductor, which has a thickness in a range of 50 to 80% based on the total thickness of the insulating coating layers and comprises a polyamide-imide resin having an adhesion-improving agent. The insulated wire of the present invention has insulating coating layers having superior coating adhesion as well as good heat-resistance.

  • Publication number: 20120247806
    Abstract: Disclosed is an insulating varnish composition including polyamideimide resin and 1 to 40 parts by weight of surface-treated silica in a sol state per 100 parts by weight of the polyamideimide resin. An insulated layer formed using the insulating varnish composition may have excellent corona discharge resistance, thereby preventing the insulation breakdown.

  • Publication number: 20120234575
    Abstract: Disclosed is an insulating varnish composition including an organo silica sol containing a silica covered with a dispersant in a solvent containing N-methyl-2-pyrrolidone (NMP) as a main component and a polyamidimide resin dispersed in a solvent containing NMP as a main component. An insulated layer formed from the insulating varnish composition containing inorganic insulating particles of silica uniformly dispersed therein may have excellent corona discharge resistance, thereby preventing the insulation breakdown.
